PIERRE SURET AND CHARLES GUILLAUME GRANDJEAN, OF BORDEAUX, FRANCE.

ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 647,338, dated April10, 1900. Application filed August 19, 1898. Serial No. 689.052. (Nomodel.)

To all whom it may concern:

Be it known that we, PIERRE SURET and CHARLES GUILLAUME GRANDJEAN,citizens of the French Republic, residing at 81 Cours St. Mdard,Bordeaux, France, have invented certain new and useful Improvements inApparatus for the Production of Acetylene Gas; and we do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The present invention relates to apparatus for generating acetylene gasfrom calcium oarbid; and the invention consists in the improvedgas-generator hereinafter described. It further consists in novel meansor apparamatically feeding the carbid.-

Our improved apparatus that is to say, the generator proper-has the,general form of a vat and is sealed at the top by a hermetically-closedcover, provided with any suitable means for the introduction of thecarbid. Below the cover is arranged a series of buckets which rotate ona central axis or shaft directly below the charge-opening. Motion isimparted to said shaft from a counter-shaft located above the vatthrough the medium of bevel-gears, said counter-shaft being itselfoperated by means of a star-wheel which is moved by the impact of a pawlcarried on the bell of the gasometer. The buckets are each provided witha strip which upon their rotation impinges against a stationary part ofthe vat and upsets the buckets.

The invention is illustrated in the drawings accompanying and forming apart of this specification, wherein- Figure l is a Vertical sectionthrough the apparatus; Fig. 2, a plan view, the top of generator and theoperating mechanism being omitted. Fig. 3 shows details of the bucketdevices, and Fig. 4 is a detail of the starwheel.

Referring to the drawings and tothe letters of reference marked thereon,A designates the generator proper, and B its cover, which is providedwith a stufling box a, through which passes a vertical shaft d, whichrotates in the socket-bearing e and carries a plurality of buckets g.Said buckets are loosely mounted on pins fin suitable supports h Z,arranged in the form of a circle on the spokes t', and each is laterallyprovided with a stem 3', projecting therefrom at an anter in the falsebottom eventually-becomes saturated with lime and can be discharged.from a tap U.

The gas-holder comprises the vat G, filled with water to the level n,and the bell or gasreceptacle 0. The bell is guided in its upward anddownward movements by two lugs s s, sliding on stationary angle-ironstandards 8 s, and by a rod 25, secured to the bottom of the vat and tothe cross-bar u, connecting the two standards. Said rod t is received inthe central tube 25, soldered to the top of the gasreceptacle. A neck Ton top the bell permits the escape of air present in the receptacle andalso the introduction of a layer of oil to isolate the gas from thewater.

Motion is transmitted to the vertical shaft 01 from a counter-shaft c,mounted in bearings b above the generator, through the medium ofbevel-gears P. A ratchet-tooth m at one end of said shaft 0 prevents thesame from turning in the wrong direction. A star wheel R is carried atthe opposite extremity of said shaft, said star-Wheel beingintermittently turned by the impact of a pawl Q), mounted on the yoke00, secured to the bell of the gasometer. When the bell ascends, thepawl bears against one of the points of the star-wheel, inclines, andpasses ofi. As the bell descends the pawl presses on the star- Wheel andforces it down one point, thereby causing the overturning of one bucket.

The apparatus operates as follows: Aquantity of carbid equal to thecapacity of one of the buckets is dropped through opening T directlyinto the water. Gas isat once generated and emanating from the generatorpasses through a purifier E through the medium of pipe q, the end ofwhich pipe is beveled and perforated like a hose-nozzle-and extends tonear the bottom of said purifier. Here the gas is injected into a layerof water or other liquid and conducted by a pipe r to the generator. Aport T is used to introduce the liquid and the tap U serves to dischargethe same. Weights v are employed to regulate the pressure. The gas isled out of the gasometer for consumption through a tube 0", providedwith a tap M, to the desiccator D, which is a cylindrical reservoirhaving a perforated bottom 19, on which rests a'quantity: of loosecotton or equivalent material powdered'with chlorid of calcium. Theremoval of plug T permits the introduction of these materials, while thepipe T2 allows the passage of the gas into the distributing-pipes. Whena diminution of pressure'occurs,the bell'descends, the star-wheelisturned by im pact of the pawl, and the operationcon tinues, as hereindescribed, the buckets having previously been filled'with carbid.

Having thus described our invention, what we claim, and desire to secureby Letters Patent of the United States, is-

1. In an acetylene-gas generator, the com-' bination with a receptaclefor water, of a car bid-container located above the same comprising arevoluble circular frame having a series of buckets pivotally mountedtherein on-axes substantially radial of the said frame, Y

and stationary means engaged by the buckets in the revolution of thecontainerto auto-.

matically and successively upset said buckets, substantially asdescribed.

2. In an acetylene-gas generator, the combination with a receptacle forwater, of a rod revolubly mounted in said generator, a gasholder havinga bell, means operated by the movement of the bell for revolving saidrod, a carbid-container mounted on said rod to turn therewith andcomprising a circular frame having a series of buckets pivotally mountedtherein on axes substantially radial of the said frame, and stationarymeans engaged by the buckets in the revolution of the container toautomatically and successively upset said buckets,substantially asdescribed.

3. In an acetylene-gas generator, the combination with 'a receptacle forwater, of a rod revolubly mounted in said generator, a counter -'s'haftabove the generator, operatively connected with said rod, a star-wheelrigid. on said counter-shaft, a gas-holder having a bell, means operatedbythe movement of the bell for revolving the star-wheel, acarbidcontainer mounted'on said rod to turn therewith and comprisinga'circular-frame having a series of buckets pivotally mounted therein onaxes substantially radial of the said frame, and stationary meansengaged by the buckets in the revolution of the container toautomatically and successively upset said buckets, substantially-asdescribed.
